Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a sieve incorporated in a shiitake mushroom sorter.

Currently, the selection of shiitake mushrooms is based on almost uniform nationwide standards.

Generally speaking, the sorting method is to run the IX on a belt conveyor and sort it into large leaves, middle leaves, small leaves, and folded leaves by many people, or to use hexagonal hole baskets or vinyl baskets with round holes to manually sort them. I'm sifting through it.

By the way, the former method, in which dried shiitake mushrooms are sorted by a large number of people using a belt conveyor, often results in products that do not meet the standards and must be re-sorted, resulting in a failure rate, while the latter method, in which dried shiitake mushrooms are sifted using a basket, is extremely brittle. Moreover, since the amplitude of the sieving is large, the mushrooms are crushed and cracked and chipped, which not only deteriorates the quality but also requires heavy labor.

There are proposals to improve efficiency by mechanically sifting shiitake mushrooms, but the long legs of shiitake mushrooms get caught in the standard holes and stop the flow, so this cannot necessarily be said to be highly efficient.

This invention solves the drawbacks of the conventional sorting methods described above, and its purpose is to provide an automatic sorting method in which mushrooms are passed through mechanically. be.

The structure of the present invention will be described below with reference to the accompanying drawings. Fig. 1 is a side view of an example of a shiitake mushroom sorting machine, and Fig. 2 is a plan view of the same, in which 1 is a lift-type shiitake mushroom supply stand, 2 are delivery belt conveyors, A-+, A-g.

A-a is the sieve of the present invention, which is a four-stage sieve of large leaves, middle leaves, small leaves, and shaking.

The sieves A-+, A-2, and A-11 are fixed to a frame 5 supported by a frame 3 via a spring 4, and are subjected to vibration by a vibrator 6.

A receiving chute 7 is connected to these sieves, and the sieve A-
A swinging shoe) 7a is provided below s, and the first receiving chute 7 faces the belt conveyor stage 9 via the parts feeder 8.

Note that the tip of the trough 10 from the parts feeder is brought to the negative side of the belt conveyor 9 in the width direction, and the tip of the trough 10 from the parts feeder is
Non-standard mushrooms are taken out to the other side in the width direction of the belt conveyor by visual selection, and each mushroom is placed in a receiving chute 11.
It is then put into the receiver 12.

Alternatively, the lift-type shiitake mushroom feeding stand 1 may be eliminated, and the feed-out pelt conveyor 2 may be a long one, and the mushrooms may be fed directly to this conveyor from the floor.

The sieves A-+, A-2, and A-s are rectangular plates 13a, as shown enlarged in FIG. 3 and further enlarged in FIGS. 4 and 5.

Cut holes 14a, 14b, 14C of a predetermined size are formed on the entire surfaces of the plates 13b and 13c at appropriate intervals, and notches 15 that become narrower in order are formed by punching toward the inclined F side of the plate. At the same time, the punched plate piece 16 is continuous with the plate body only at the tip which gradually becomes narrower, and the punched plate piece 16 is slightly inclined downward, and the inclined lower side a
is further curved downward. The illustrated punched plate piece has the hole side half cut out.

Although the sieve holes 14a, 14b, and 14C are circular in the figure, they can also be polygonal.

The present invention has a structure as described above, and this sieve has a notch facing in the direction of the inclination r of the sieve following the sieve drop hole formed in the plate body, and the large side of the sieve drop is deep in the other notch. The sieve has a bottom plate (punched plate piece) that becomes shallower toward the upper side of the slant, so mushrooms that partially enter the sieve hole but do not fall out can be removed even if the mushroom's foot has entered the hole. This foot is successively pushed up by the bottom plate (punched plate piece) and pushed out from the notch, so that 1<
The effect is that there is no risk of the legs of the mushroom getting caught in the sieve pit and stopping the flow.The legs of shiitake mushrooms are not necessarily straight, some curve to the side, and some have relatively long legs. , When these legs enter the gap @17 between the lower side edge of the notch 15 and both side edges of the punched plate piece 16 at the notch in the sieve hole, this gap becomes smaller as it reaches the upper side of the sieve's slope. There is a risk that the mushroom legs may get caught in the hole, but this gap 1
7 is closed with the side wall plate pieces 18, thereby preventing the legs from getting caught and having the effect that the flow of the shiitake mushrooms on the sieve can be made partially smooth and reliable.
